teststof

Teststof is a Dutch term that refers to a substance used for testing. In laboratory and research settings, a teststof is selected to evaluate methods, calibrate instruments, or demonstrate chemical properties. The concept is common in Dutch technical and scientific writing and is used across disciplines such as chemistry, pharmacology, and materials science.

Etymology and usage: The word combines test and stof (substance). It denotes a material chosen for experimental purposes rather than for consumption or sale. In English-language contexts, the closest equivalents are "test substance" or "reference material," with precise meaning depending on the field.

Applications: Teststoffen are employed to validate analytical methods, assess the performance of equipment, or train personnel. They may be inert references, standards with known purity, or chemicals with defined properties used to compare results. In product development and quality control, teststoffen help establish benchmarks and ensure repeatability of measurements.

Safety and handling: As with any chemical substance, teststoffen should be managed according to applicable safety guidelines. This includes proper labeling, storage, and disposal, as well as consulting safety data sheets and following institutional or regulatory requirements. Hazard classification depends on the specific substance involved.
